DM510 - DM518 LOW FLOW PRESSURE REDUCING REGULATOR

Self-acting pressure reducers are simple control valves offering accurate
control while being easy to install and maintain. They control the
pressure downstream of the valve without requiring pneumatic or
electrical control elements.

The DM 510, DM 511, DM 514, DM 515, DM 516 and DM 518
pressure reducing valves are diaphragm, piston or bellows-controlled
spring-loaded proportional control valves for high inlet and outlet
pressures. They can be supplied with three types of connections:
sockets, flanges and welding spigots. Each size of valve may be fitted
with three different seats. The valve cone may be fitted with a soft or
metallic seal.

The outlet pressure to be controlled is balanced across the control unit
by the force of the valve spring (set pressure). As the outlet pressure rises
above the pressure set using the adjusting screw, the valve cone moves
towards the seat and the volume of medium is reduced. As the outlet
pressure drops, the valve control orifice increases; when the pipeline is
depressurised, the valve is open. Rotating the adjusting screw clockwise
increases the outlet pressure.

These valves are no shut-off elements ensuring a tight closing of the
valve. In accordance with DIN EN 60534-4 and/or ANSI FCI 70-2 they
may feature a leakage rate in closed position in compliance with the
leakage classes III or V, optional IV:
